“…Within the last five years some researchers have raised concerns that the use of REOB in bitumen has led to early pavement cracking. Tests have been developed by Hesp and his co-workers to identify bitumen properties believed to be related to the presence of REOB and indicative of poor pavement performance (Hesp S. &., 2010) (Rubab, 2011).…”

The use of vacuum distilled residues from the re-refining of used motor oils as blend stock in paving grade bitumen has occurred in isolated markets in North America for more than 30 years. Recently in the United States the increasing need for low stiffness bitumen for use in high binder replacement mixtures, coupled with economic considerations, has led to an expanding market for these products. Little in-depth investigation into the long-term impact of these additives on mixture performance has taken place until recently. Conflicting studies from researchers in Canada and private organizations have been published. Here, we review the eight-year performance of four virgin mixture test sections placed on a county highway Minnesota. Three test sections used PG 58-28 bitumens from different crude sources, one of which contained approximately 8% of the re-refined engine oil residuum. The fourth utilized PG 58-34 polymer-modified bitumen. Pavement distress surveys were conducted over the eight year period. Tests of the original bitumen following extended laboratory aging were conducted. Properties of the recovered bitumen from eight-year-old field cores were correlated to pavement distress. Double Edge Notched Tension (DENT) tests were conducted on 20-and 40-hour PAV residues of the original bitumen. Iatroscan and extensive rheological testing were conducted on laboratory aged bitumen and on bitumen recovered from laboratory aged mixtures and field cores to determine the colloidal index, rheological index and the extent to which laboratory aged and recovered bitumen materials were m-controlled. Also evaluated were three test sections constructed at the Minnesota DOT MnROAD test site. A comparative study of and PG 58-40 (PMA +re-refined engine oil bottoms) were evaluated over eight years. Bitumen used on the projects was tested as described above. The PG 58-40 exhibited the worst performance. The results of binder evaluations correlated to the fatigue cracking observed in the field with the test sections containing the re-refined engine oil residuum exhibiting the most extensive fatigue cracking. Based on this investigation we provide recommendations for test criteria to identify bitumens that could increase an asphalt mixture's likelihood to exhibit poor durability and fatigue cracking performance.

“…Research by Hesp et al (Hesp andShurvell 2010, Burke andHesp 2011) has shown that the use of waste engine oil residue can be used to extend the binder performance grade. However, the use of such oils caused physical and chemical hardening of binder and premature excessive thermal cracking of asphalt pavements in Ontario province in Canada, and therefore the authors do not advise the use of WEO residue as rejuvenators.…”

Asphalt is the most recycled material in the USA at a re-use rate of 99%. However, by average only 10 -20% reclaimed asphalt pavement (RAP) is used in a given mix design and large part of the RAP is degraded for use in lower value applications. The amount of RAP in asphalt mixtures can be significantly increased with the application of good RAP management practice, readily available modern production technologies and advanced knowledge of mix design. This paper summarises the state-of-the-art approaches for increasing the amount of RAP in asphalt mixtures above 40%. The production challenges and common pavement distresses of very high RAP content mixtures are identified and methods to optimise the mix design as well as production technology in order to allow manufacturing of such sustainable mixtures are described. The best practices for RAP management and economic benefits of high RAP use are also discussed.

“…rough X-ray fluorescence analysis in Canada, Hesp and Shurvell [9] confirmed that REOB can be used in asphalt binders and discussed the adverse effects of REOB on the early cracking of asphalt pavement. Rubab et al [10] conducted rolling thin film oven (RTFO) and pressure ageing vessel (PAV) tests after mixing REOB with two different types of asphalt binders in Canada and found that REOB may accelerate the oxidation speed of modified asphalt while improving the performance grade of asphalt binders.…”

Numerous environmental pollution and resource waste problems are associated with recycled engine oil bottom (REOB), which cannot be effectively recycled. Based on the similarity compatibility theory and component adjustment theory, comparing the physical and rheological properties of laboratory-aged asphalt under three types of REOB (defined as REOB-1, REOB-2, and REOB-3) with different dosages, the optimum type and dosage of REOB as asphalt regenerant were explored. The rejuvenation mechanism of REOB on aged asphalt was revealed by combined performance, four-component, and infrared spectroscopy analyses. The relationship between the four components and physical rheological indexes in the process of asphalt rejuvenated by REOB was quantitatively obtained by the grey relationship analysis. The results show that only REOB-3 with a dosage of 7% on the aged asphalt has the best comprehensive rejuvenation effect. Also, the high-temperature rutting resistance of rejuvenated asphalt with 7% REOB-3 is better than that of the original asphalt, but the low-temperature flexibility and the crack resistance performance have yet to be improved. The mechanism through which REOB rejuvenates aged asphalt is an incomplete component adjustment; some of the components undergo physical or chemical reactions and transformations. Accordingly, the asphaltene content and the intensity of sulfoxide functional groups in aged asphalt decrease, thereby achieving rejuvenation gradually with the addition of REOB. A grey relationship analysis demonstrates that asphaltenes have the greatest influence on high-temperature performance and that low-temperature performance requires a reasonable combination of four components. Moreover, a comprehensive advantage analysis reveals that REOB is the most sensitive to the softening point and that the asphaltene content has the greatest influence on the physical and rheological properties of REOB-rejuvenated asphalt. Therefore, the asphaltene content should be strictly controlled during the addition of REOB to rejuvenate aged asphalt.
